For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In the related art, drones can carry spreading equipment to carry out crop spreading operations. The spreading equipment usually includes a mounting shell, a feeding mechanism and a spreading mechanism arranged on the mounting shell. The feeding mechanism is used to transport materials to the spreading mechanism, and the spreading mechanism is used to spread the materials output by the feeding device to complete the spreading operation. However, since the materials required for crops may be materials such as fertilizers or liquid medicines with high viscosity, the materials with high viscosity are easily deposited in the feeding mechanism and even adhere to the mounting shell, making the cleaning operation of the entire spreading equipment more complicated, with problems such as low cleaning efficiency, poor cleaning quality, and high maintenance costs.

[0041] In view of this, this embodiment arranges the feeding mechanism of the drone and the mounting shell to be engaged with each other through a card slot and a card piece, which not only improves the convenience of installation, disassembly and maintenance operations, but also facilitates cleaning operations, which is conducive to ensuring the cleaning quality and cleaning efficiency, so as to fully reduce the maintenance and use costs. The structure of the drone is described in detail below.

[0042] Figure 1 The structure of the spreading device 100 provided in this embodiment is shown in FIG. Figure 1 ; Figure 2 The structure of the spreading device 100 provided in this embodiment is shown in FIG. Figure 2 ; Figure 3 A partial exploded schematic diagram of the spreading device 100 provided in this embodiment Figure 1 ; Figure 4 A partial exploded schematic diagram of the spreading device 100 provided in this embodiment Figure 2 . See Figures 1 to 4 This embodiment provides a drone, which includes a frame (not shown in the figure), a sowing device 100 and a storage device (not shown in the figure).

[0043] In detail, the frame is the main structure of the entire UAV, which is used to install the sowing equipment 100 and the storage equipment to provide guarantees for flight operations and sowing operations. The sowing equipment 100 is a sowing structure installed above the frame, which can perform sowing operations of materials such as medicines and seeds to meet the sowing needs of crops and ensure sowing efficiency and quality. The storage equipment is arranged above the sowing equipment 100, or directly arranged above the frame, and is used to transport materials to the sowing equipment 100, so that the sowing equipment 100 can continuously sow materials, thereby further ensuring sowing efficiency and ensuring the normal growth of crops.

[0044] Please refer again Figures 1 to 4 In this embodiment, the spreading device 100 specifically includes a feeding device 102 and a spreading device.

[0045] In detail, in this embodiment, the feeding device 102 includes a mounting shell 104 and a feeding mechanism. The mounting shell 104 is used to be mounted on the frame, and a feed inlet 105 is provided above the mounting shell 104. The storage device is specifically mounted on the mounting shell 104 and is located above the feed inlet 105, so as to transport the material to the feeding device 102 through the feed inlet 105 to ensure the feeding and spreading requirements. The feeding mechanism is arranged in the mounting shell 104 and is connected to the feed inlet 105, and can output the material input from the feed inlet 105 for spreading by the spreading device.

[0046] In more detail, a first matching portion 119 is provided on the mounting shell 104. The feeding mechanism specifically includes a feeding shell 109 and a feeding member 127. The feeding shell 109 is at least partially detachably plugged into the mounting shell 104, and a second matching portion 121 matching with the first matching portion 119 is provided on the feeding shell 109. At the same time, the feeding shell 109 is provided with an inlet 115 and an outlet 117. When the first matching portion 119 matches with the second matching portion 121, the inlet 115 is connected with the feed port 105. The feeding member 127 is movably provided in the feeding shell 109, and is used to transport the material input from the inlet 115 to the outlet 117, and the outlet 117 is used to output the material. On the one hand, since the installation shell 104 and the feeding shell 109 are detachably plugged together, no fasteners such as screws are required, so the convenience of installation, disassembly and maintenance between the installation shell 104 and the feeding shell 109 can be effectively improved, which can improve the work efficiency and reduce the maintenance cost. On the other hand, since the entire feeding shell 109 can be disassembled relative to the installation shell 104, it can also facilitate the cleaning operation after the feeding shell 109 and the installation shell 104 are disassembled, which can reduce dead angles and thus improve the cleaning efficiency and quality. At the same time, when the first matching portion 119 and the second matching portion 121 are matched, the inlet 115 is connected to the feed port 105, so the matching of the first matching portion 119 and the second matching portion 121 can also be used as a positioning indicator for the matching of the inlet 115 and the feed port 105, so as to ensure that the material input into the inlet 115 can be accurately input through the feed port 105, thereby ensuring the feeding quality and effect.

[0047] That is, through such a setting, not only the convenience of installation, disassembly and maintenance operations can be improved, but also the cleaning operation can be facilitated, which is conducive to ensuring the cleaning quality and cleaning efficiency, so as to fully reduce the maintenance and use costs.

[0048] In detail, in this embodiment, one of the first matching portion 119 and the second matching portion 121 is a card slot, and the other of the first matching portion 119 and the second matching portion 121 is a card member, and the card member is engaged with the card slot. The card member and the card slot can further facilitate the installation, disassembly and maintenance operations, and can further improve the work efficiency and quality. However, in other embodiments, when the feeding shell 109 is at least partially detachably plugged into the installation shell 104, one of the first matching portion 119 and the second matching portion 121 can also be set as a plug-in column, and the other of the two can also be set as a plug-in hole for plug-in cooperation, or one of the two can also be set as a hook, and the other of the two can also be set as a card portion for hook cooperation, or both can be set as magnetic parts for magnetic cooperation; even, it can also be selected to be fastened and connected in the form of bolts, which can fully ensure the reliability and stability of the installation, disassembly and maintenance operations of the sowing equipment, and this embodiment will not be repeated.

[0049] In more detail, in the present embodiment, the spreading device is arranged adjacent to the feeding shell 109, and the spreading device is specifically connected to the outlet 117 of the feeding shell 109, so that when the spreading operation is performed, the material output from the storage device to the feeding device 102 can be output to the spreading device through the outlet 117, thereby facilitating the spreading device to spread the material output from the outlet 117.

[0050] Figure 5 for Figure 4 Please refer to the enlarged view of the part I of Figures 3 to 5 In this embodiment, the feed housing 109 and the mounting housing 104 are both roughly cylindrical in structure, and the mounting housing 104 is sleeved outside the feed housing 109, the first end of the feed housing 109 extends out of the mounting housing 104, and the second end of the feed housing 109 is roughly flush with the end of the mounting housing 104. The first matching portion 119 is specifically a circumferential card slot opened on the inner side wall of the mounting housing 104, the card slot is an arc-shaped card slot, and is a recessed groove recessed toward the outer side wall of the mounting housing 104, and at the same time, one side of the card slot has a notch 123, so that the entire card slot is roughly arc-shaped "L" shape. Correspondingly, the second matching portion 121 is a card member convexly arranged outside the feed housing 109, the card member is arranged in an arc-shaped protruding structure, and extends in a direction away from the feed housing 109 to match with the card slot. Furthermore, the specific matching process between the card member and the slot is that the card member can enter the slot through the notch 123 and rotate along the extension direction of the slot to stably engage with the slot. That is, the matching between the feeding shell 109 and the installation shell 104 only requires that the feeding shell 109 is set in the installation shell 104, and the card member is inserted into the slot through the notch 123, and rotated along the extension direction of the slot so that the card member and the slot are engaged. There are advantages of convenient and reliable installation process, and it is also convenient to carry out disassembly and maintenance operations, thereby facilitating cleaning operations, ensuring cleaning efficiency, and reducing maintenance costs. Of course, in other embodiments, the first matching portion 119 can also be set as a card member, and the second matching portion 121 can also be correspondingly set as a slot, which will not be repeated in this embodiment.

[0051] For details, please refer again Figure 5In this embodiment, the slot specifically includes a slot bottom 125 and two slot walls 124. The two slot walls 124 are spaced apart on both sides of the slot bottom 125 along the axial direction of the mounting housing 104. The notch 123 is provided on any one of the two slot walls 124, so that the entire slot is roughly an "L"-shaped slot structure. Correspondingly, the thickness of the card piece is adapted to the distance between the two slot walls 124, so that when the card piece is matched with the slot, the card piece can first move along the axial direction of the mounting housing 104 and the feeding housing 109 to enter the slot through the notch 123, and then move along the circumferential direction of the mounting housing 104 and the feeding housing 109 to be stably clamped between the two slot walls 124.

[0052] In more detail, in this embodiment, along the circumference of the mounting housing 104, the mounting housing 104 is provided with a plurality of first matching portions 119 at intervals, for example, three first matching portions 119 are provided, and the three first matching portions 119 are arranged at intervals in a ring shape. Correspondingly, along the circumference of the feeding housing 109, the feeding housing 109 is provided with a plurality of second matching portions 121 at intervals, for example, three second matching portions 121 are also provided, and the three second matching portions 121 are also arranged at intervals in a ring shape, so that the three second matching portions 121 can be engaged with the three first matching portions 119 in a one-to-one correspondence. That is, when three first matching parts 119 and three second matching parts 121 are provided, each card member can enter the card slot at the corresponding position through the notch 123 at the corresponding position, so that when the entire feeding shell 109 is rotated, the three card members can be plugged into the card slot at the corresponding position to provide sufficient stability and limiting effect, thereby fully improving the stability of the feeding shell 109 after matching with the installation shell 104, so as to ensure the stability and reliability of the feeding operation and the sowing operation. Of course, in other embodiments, the number of the first matching parts 119 and the second matching parts 121 can also be adjusted and selected according to demand, as long as the stability of the feeding shell 109 after matching with the installation shell 104 is ensured, and this embodiment does not limit it.

[0053] Please refer again Figures 1 to 4In this embodiment, since the feeding shell 109 and the mounting shell 104 are both arranged in a cylindrical structure, the feed port 105 can be opened in the circumference of the mounting shell 104, and the inlet 115 can also be correspondingly opened in the circumference of the feeding shell 109, and opposite to the feed port 105. The outlet 117 can be specifically opened at the end of the feeding shell 109. At this time, the feeding member 127 arranged in the feeding shell 109 can specifically include a shaft body 129 arranged coaxially with the feeding shell 109 and blades arranged in a circumferential spiral around the shaft body 129. Among them, the shaft body 129 is arranged in the feeding shell 109, at least part of the blade is opposite to the inlet 115, and the shaft body 129 is configured to be able to rotate to drive the blade to transport the material input from the inlet 115 to the outlet 117. That is, through such an arrangement, after the material is output from the storage device to the feed port 105, the material can pass through the feed port 105 and the entrance 115 in sequence and then reach the blades, so that the shaft 129 can drive the blades to rotate during the rotation relative to the feeding shell 109, so that the blades can transport the material to the outlet 117, so as to facilitate the sowing operation through the sowing device connected to the outlet 117.

[0054] As an optional solution, in this embodiment, an outlet 117 is provided at both ends of the feeding housing 109, and the spreading device also specifically includes two spreading mechanisms 139, which are arranged one-to-one with the two outlets 117. At the same time, the shaft 129 is extended and arranged between the two outlets 117, and the blades include a first blade 131 and a second blade 133 which are arranged in a circumferential spiral around the shaft 129. The first blade 131 and the second blade 133 have opposite rotation directions and are at least partially opposite to the inlet 115, respectively used to transport the material input from the inlet 115 to the two outlets 117 at both ends when the shaft 129 rotates, so that the material output from the outlet 117 can be spread through the spreading mechanisms 139 at the corresponding positions. By setting up two outlets 117 and two spreading mechanisms 139, the feeding device 102 can perform bidirectional feeding, thereby greatly improving the efficiency of material transportation, and also greatly improving the spreading efficiency and amplitude of the spreading equipment 100, thereby meeting greater spreading needs of crops and ensuring the operating efficiency and quality of the drone.

[0055] At the same time, in this embodiment, the feeding mechanism also includes a driving member 135, which is installed at the end of the mounting shell 104 through a driving shell 137. The operation of the feeding member 127 is driven by the driving member 135. The driving member 135 is a driving motor. The driving motor and the feeding member 127 are connected to each other through a transmission member 136. The transmission member 136 can be selected as a transmission shaft, so that when the driving motor is running, the feeding member 127 can be driven to rotate through the transmission member 136, so that the blades rotate synchronously to transport the material input from the inlet 115 to the outlet 117, thereby facilitating the sowing operation of the sowing mechanism 139.

[0056] Further optionally, in the present embodiment, each spreading mechanism 139 is configured to be engaged with the feeding housing 109 and / or the mounting housing 104. That is, the cooperation mode between the spreading mechanism 139 and the feeding housing 109 or the mounting housing 104 is also configured to be engaged with the feeding housing 109 or the mounting housing 104, so that the convenience of installation, disassembly and maintenance of the spreading mechanism 139 can be greatly improved, and it is also convenient to clean and maintain the spreading mechanism 139, so as to improve the cleaning and maintenance efficiency and reduce the maintenance cost.

[0057] In detail, the two spreading mechanisms 139 are respectively a first spreading mechanism and a second spreading mechanism. The first spreading mechanism is used to engage with the feeding housing 109, and the second spreading mechanism is used to engage with the mounting housing 104, so as to fully ensure the stability of the spreading operation. Of course, in other embodiments, the first spreading mechanism may also engage with the mounting housing 104, and the second spreading mechanism may also engage with the feeding housing 109, which is not limited in this embodiment.

[0058] In more detail, in this embodiment, the first spreading mechanism is provided with a third matching portion 151, and the feeding housing 109 is provided with a fourth matching portion 153. One of the third matching portion 151 and the fourth matching portion 153 is a slot, and the slot structure is the same as the slot structure of the first matching portion 119 provided on the mounting housing 104. The other of the third matching portion 151 and the fourth matching portion 153 is a clamping member, and the clamping member structure is the same as the clamping member structure of the second matching portion 121 provided circumferentially on the feeding housing 109, so that the third matching portion 151 and the fourth matching portion 153 can also be engaged and matched through the clamping member and the slot. Correspondingly, the second spreading mechanism is provided with a fifth matching portion 155, and the mounting housing 104 is provided with a sixth matching portion 157. One of the fifth matching portion 155 and the sixth matching portion 157 is a slot, and the slot structure is the same as the slot structure of the first matching portion 119 provided on the mounting housing 104. The other of the fifth matching portion 155 and the sixth matching portion 157 is a clamping member, and the clamping member structure is the same as the clamping member structure of the second matching portion 121 circumferentially arranged on the feeding housing 109, so that the fifth matching portion 155 and the sixth matching portion 157 can also be clamped and matched through the clamping groove and the clamping member structure. That is, through such an arrangement, the installation, disassembly and maintenance of the first spreading mechanism and the second spreading mechanism can be conveniently and reliably carried out, and the operation efficiency and operation quality can be fully guaranteed.

[0059] Further, in the present embodiment, the feeding shell 109 specifically includes a feeding shell 111 and a connecting shell 113.
